The first known practical sensitometer, which allowed measurements of the speed of photographic materials, was invented by the Polish engineer Leon Warnerke [3] – pseudonym of Władysław Małachowski (1837–1900) – in 1880, among the achievements for which he was awarded the Progress Medal of the Photographic Society of Great Britain in 1882.
GN = distance × f-number. One needs to specify the film or sensor ISO speed, and it is conventional to quote for ISO 100/21°. The distance can be in feet or in metres, the units to be specified. [4] GND: Graduated neutral density. A type of neutral density filter in which brightness is reduced more on one side of the filter than on the other ...
Sunlit subject shot on a digital camera set to ISO 100, exposed at f/8 at 1/400 second which is the same exposure value as f/16 for 1/100 second, the recommended "sunny 16" exposure. In photography, the sunny 16 rule (also known as the sunny f /16 rule) is a method of estimating correct daylight exposures without a light meter. Apart from the ...

ISO 732 is an ISO standard for medium format photographic film. The second (1982) edition of the standard specified the dimensions for 127 , 120 and 620 roll film, backing paper and film spools. The third (1991) edition dropped specifications for the 127 and 620 roll films, which had become largely obsolete in the photography industry and added ...

It has developed various standards, which have been published by ITU-T and/or ISO/IEC. The standards developed by the JPEG (and former JBIG) sub-groups are referred to as a joint development of ISO/IEC JTC 1/SC 29/WG 1 and ITU-T SG16. The JPEG standards typically consist of different Parts in ISO/IEC terminology.
Medium format digitals such as this are geared more towards studio and portrait photography than their smaller DSLR counterparts; the ISO speed in particular tends to have a maximum of 400, versus 6400 for some DSLR cameras. (Canon EOS-1D Mark IV and Nikon D3S have ISO 12800 plus Hi-3 ISO 102400 with the Canon EOS-1Dx's ISO of 204800).
